</div>Do you have the video preview running? That eats up a bit of CPU IIRC.<br>

</div></div></blockquote></div><br>I had all of these problems and just got my myth frontend working about 1 hour ago...It's going through the Wife test right now.<br><br>I have a 2.2 Dual core with an NVidia 8400 GS DVI hookup to a 1080i TV. And the NVidia 180.16 driver.<br>
<br>First off 0.21 will not work. You have to compile it yourself. It took me a little bit but once I got the compiling figured out I started tweeking. The first few compiles I did I saw X and Myth FE taking ov er the CPU both 57/43%...So CPU was high always....Even when not playing video.<br>
<br>First I started with Mythbuntu 8.10 which includes Myth 0.21. Got that working (db setup and all). Then I removed everything myth (plugins, thems, web, frontend, backend) I left the DB, and Mythbuntu scripts (init.d type stuff). So the /usr/lib, /usr/share/mythtv, /usr/bin didn't have anything myth (excluding mythbuntu items) in them. <br>
<br>Next I started playing around with the compiler using SVN Trunk 19597. I compile write on this box. Here are the settings I eventually ended up using.<br><br>MythTV<br>./configure --prefix=/usr --enable-proc-opt --disable-joystick-menu --disable-firewire --disable-hdhomerun --disable-xvmcw --enable-xvmc-opengl --enable-vdpau --disable-directfb --enable-opengl-vsync<br>
<br>MythPlugins<br>./configure --prefix=/usr --enable-opengl --enable-mytharchive --disable-mythbrowser --disable-mythcontrols --disable-mythflix --enable-mythgallery --disable-mythgame --enable-mythmusic --disable-mythnews --disable-mythphone --enable-mythvideo --disable-mythweather --disable-mythzoneminder --disable-mythmovies<br>
<br>Now I then used <br> sudo checkinstall <br>to create .deb packages (using mythbuntu 8.10 as my base). I then use <br> dpkg -i <package><br>to install them.<br><br>Then started testing... First you have to setup the playback profile to use the VDPAU settings. Next I try watching a recording. Still stuttered but my 100% CPU dropped to 9% for the frontend and 1% for X. So looks good but still stuttering. Next I moved on to looking at the logs....I ran with <br>
<br>Now I started working on the interlacers.<br><br>frontend -v playback >& /var/log/mythtv/frontend.log<br><br>So I saw the deinterlacer wasn't working properly... So I kept tweaking that setting. Finally I settled on Advance (2x, HW) because of something I read on the wiki... (keep reading though before jumping on this one).<br>
<br>Still stuttered but then I noticed in the log a lot of audio issues and buffer overrunds. That led me down an audio path. So I worked with that for a days trying to et digiital playback. Never got that to work and just set it to ALSA;hw:0,0<br>
<br>So then I went back and worked on playback. I end up setting the deinterlacer to One Field (1x, Hw) and None for the secondary....<br><br>Now everything is working perfectly.<br><br>I hope that this helps and sorry it was so long.<br>
